CERESIT CT 83 SUBSTRATE PREPARATION

CERESIT CT 83 shows very good adhesion to sound and carrying substrates, such as wall, plaster and cement substrates free from grease, bitumen, dust and other substances decreasing adhesion. The adhesion to the existing plasters and paint coatings should be checked before starting the application. Any surface contaminant and other adhesion impairing substances, steam-tight paint coatings and the coats with low adhesion to the substrate should be completely removed.

APPLICATION OF CERESIT CT 83

CERESIT CT 83 should be poured into water and stirred with the drill by means of a mixer until the homogenous mass is obtained. The ready mortar should be applied with a trowel along the board edges. Then immediately, the board should be pressed to the wall. When CT 83 is set (after approx. 3 days), any unevenness of the boards should be ground with abrasive paper, then the boards should be additionally reinforced with mechanical anchors.

IMPORTANT TO NOTE WHEN USING CERESIT CT 83

CERESIT CT 83 powder mortar shows acrid properties, and cement and lime content causes alkali reaction when mixed with water. Skin and eyes should be protected. In case of contact with eyes, they should be rinsed with water and a general practitioner should be consulted.
